We're dividing 663804 by 1 
We're looking to find how many times 1 goes into 663804.

Let's proceed to step 1:
1 can be fit into 6 6 times, resulting in a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
The remainder is 0 after subtracting 6 from 6.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 1

Let's proceed to step 2:
If we divide 6 by 1, we get 6 and a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 66.0
If we subtract 6 from 6, we get 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 1

Going ahead to step 3:
When dividing 3 by 1, we get 3 with a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 663.0
If we take 3 away from 3, we end up with 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 1

Going ahead to step 4:
When dividing 8 by 1, we get 8 with a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 6638.0
Deduct 8 from 8 and we're left with 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 1

Let's proceed to step 5:
0 divided by 1 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 66380.0
Subtracting 0 from 0 leaves us with 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 1

Moving on to step 6:
The number 1 fits into 4 4 times, leaving a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 663804.0
If we subtract 4 from 4, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 7:
1 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 663804.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
If we divide 0 by 1, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 663804.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 663804.0 and a remainder of 0.0.
